Demons and Etherious carry Demon particles within them; Mirajane Strauss also possess these particles, which she called the "Demon Factor" and explained that it was required for the use of her signature Magic; this Demon Factor is also used by members of Tartaros to turn humans into Demon hybrids, though the only known successful cases were Doriate, Minerva Orland, and her father.[3]

Magic and Abilities

Demons have a number of Magic and abilities, though it varies from Demon to Demon. The subspecies known as Etherious prefer to use Curses, rather than Magic.[4]
